Portable Signal Analyzer |
|
Marketing Information |
|
The SA 1454 provides you with a
full-featured spectral display for finding and analyzing both analog and
digital signals. Plus, it provides you with both signal leakage and
ingress testing capabilities for complete signal testing confidence. |
|
Features |
- Full tuning capabilities from 5 to
870 MHz for testing both forward and reverse path testing and
troubleshooting.
- Fully featured spectral display
for viewing your full channel line-up or a specific carrier or
frequency to isolate signal problems.
- Analog signal testing parameters
that include RF level, C/N, A/V ratio, and audio output levels.
- Digital signal parameter testing
that includes average peak power, bBer, and digital peak to valley
measurements to ensure digital signal quality.
- Signal Leakage and Ingress testing
capabilities to track down signal interference that can cause
serious digital signal problems and ensure good quality signals at
every drop.
- Data logging and printing
capabilities for system documentation and future drop point
comparisons. Plus, built-in voltmeter for quick voltage testing
through the coax for cable modem and telephony installs.
